Abstract

Objective: To determine the value of computed tomography (CT) scans for preoperatively detecting extrauterine-nodal disease and postoperative recurrent disease in patients with endometrial cancer. Methods: We reviewed records of 702 women with primary endometrial carcinoma that was diagnosed between 1979 and 1993. Preoperative CT findings were compared with pathologic findings to assess nodal disease. The yield of postoperative CT was reviewed in clinically suspicious and routine settings. Results: Among 492 women eligible for analysis, 178 (36%) had a total 326 CT scans. Among 56 women who had preoperative CT scans and lymph node samplings, positive and negative predictive values for nodal involvement were 50% and 94%, respectively, and sensitivity and specificity were 57% and 92%, respectively. Preoperative CT findings altered treatment plans in only six patients (8%). Forty-five asymptomatic women had 73 routine CT scans, and recurrence was diagnosed by CT in only two (4.4%). Thirty-seven women had CT scans for suspicion of recurrence, which was confirmed in 17 (46%). Kaplan-Meyer analysis showed no survival advantage in women with subclinical recurrences diagnosed by CT scan. Conclusion: Routine preoperative CT scanning rarely alters treatment and is a poor predictor of nodal disease. Computed tomography in the postoperative period might be helpful for detection and follow-up of recurrent disease, but there was no difference in survival when subclinical recurrence was found by CT. Thus, CT scanning of any woman with endometrial cancer should be discouraged unless it is to evaluate symptoms. Copyright (C) 2000 The American College of Obstetricians and Gynecologists.
